Summary :
When updating the class value assignment in the material master, issues such as deadlocks or performance degradation can occur during subsequent planning file entries update. This is evident as the system hangs in SAPLDISP or extended lock situations are observed on the MDVM/DBVM tables. The problem roots from individual instead of collective updates to MDVM during the write process. The proposed solution mandates implementing program corrections that facilitate collective updates for planning file entries after a class value adjustment in the material master.
Key words :
table mdvm/dbvm remain, terms planning file entry, writing planning file entries, planning file entries, attached program corrections, collective update occurs, collective update, program sapldisp, subsequent update, individual update
